Please help! Wangler 4.0 cut out wont re start

Hi, thanks for looking and i just hope someone can help me
I have searched everywhere and cant find a solution to my problem.

1997 Wrangler (right hand drive uk import) 4.0 Sahara manual. 90k on the clock

I was leaving my house when she just died, no splutter or cough just cut out.
I am a HGV technician but im running out of ideas and probably missed the fault along the line.

I don't have a spark
The dash gauges dont work (amp-meter, fuel level, rev counter ect)
And the weird one is the Fuel pump constantly runs with ignition on as in it doesn't cut out after 3 second prime

I have got power to all the relays and fuses
got power to the coil
checked and fitted extra earth straps
New heavy duty battery
Fitted a new crank sensor (cps)
fitted uprated coil, HT leads, spark plugs, new distributor cap and arm.

I even unplugged the fuel pump multi plug to see if it was a short there somewhere.
I am starting to think it could be the engine ECU/control module? if so will any ecu from another 4.0 wrangler work on her?

Any ideas or advice would be much appreciated guys

Thanks for taking the time to read this

Hawkeye

this happened to me once and it turned out to be a bad connection to the battery. take both cables off each post and clean the hell out of them, then make sure they are tight and right. good luck!
